摘要
本研究聚焦于北山地区园包山钼多金属矿床,综合分析了其地质背景、矿床特征及成矿机理.北山地区处于西伯利亚、哈萨克斯坦与塔里木板块交汇处,园包山钼矿点位于此一复杂构造地质单元的北边缘.通过对区内矿体与矿石特征的研究,揭示了中高温与中低温热液活动共存的矿化特征,表明该区经历了多期矿化流体活动.特别是在NWW向断裂带及其邻近的侵入体区域,发现了显著的地表矿化现象和深部激电极化率异常,暗示深部存在规模较大的岩浆热液活动.研究结果表明,园包山矿床具备斑岩型成矿特征及良好的成矿潜力.建议在北山北缘进一步开展勘查工作,以期在该地区取得重要的钼矿找矿突破,为矿产勘探提供重要参考.
Abstract
This study focuses on the Yuanbaoshan molybdenum polymetallic deposit in the Beishan area,providing a comprehensive analysis of its geological background,deposit characteristics,and ore-forming mechanisms.The Beishan area is located at the junction of the Siberian,Kazakhstan,and Tarim plates,with the Yuanbaoshan molybdenum deposit situated at the northern edge of this complex tectonic-geological unit.Research on the area's ore bodies and mineral characteristics has revealed the coexistence of mid-high temperature and mid-low temperature hydrothermal activities,indicating multiple phases of mineralizing fluid activity.Notably,in the NWW-oriented fault zones and adjacent intrusive bodies,significant surface mineralization and anomalies in deep electrical polarization suggest the existence of large-scale magmatic hydrothermal activities.The results indicate that the Yuanbaoshan deposit has porphyry-type mineralization features and significant ore-forming potential.It is recommended to further explore the northern edge of Beishan to achieve significant breakthroughs in molybdenum prospecting in the area,providing an important reference for mineral exploration.
